During shooting in sub-zero temperatures, Leni Riefenstahl developed severe frostbite and a bladder infection that would plague her for the rest of her life.
One of the avalanches seen in the film was real and was captured on camera on the spot. It was a threat to cast and crew as well, nearly burying them alive.
Director Arnold Fanck took the film to Universal Pictures but they felt that the script was too thin and turned it down, so Fanke financed the production himself.
In the film Inglourious Basterds (2009), when Shosanna is changing the marquee at the cinema, this is the film being advertised on the marquee that she is taking down to replace with the Max Linder festival.
Leni Riefenstahl complained that director Arnold Fanck put her through a grueling shoot and claimed that he was deliberately cruel to her. Nevertheless, the film would be her most critically acclaimed performance.
